I think I need to rephrase myself a bit.

Like if you have 100 patches merged and 2 rechecks, even if all of them are
bare, doesn't mean that developers don't care about resources. It's more
then they are so sure in their tests stability, that they absolutely sure
it's infra failure.
Or vice versa, if there are 20 rechecks for 2 patches, even if neither of
them are bare, it's still weird and smth worth reconsidering from project
perspective.

I hope I explained better now what I meant.
